[[WCAG2]] Success Criterion 2.4.6 + currently states that all headings must describe their topic or purpose. The implication of this + wording is that all chapters in a novel, for example, have a topic or purpose and that the topic + or purpose is always clearly reflected by the title of the chapter. Not only is this not always + the case, but this success criterion also complicates the use of chapter numbers as headings + since these do not establish a topic.
+ +After discussion in the Accessibility + Guidelines Working Group's issue tracker, it is clear that the understanding + document for 2.4.6 captures the intent of the success criterion better than the current + wording — namely, that the requirement for headings is only that they establish a unique + context for the content.
+ +By this interpretation, the headings in publications should always pass provided they are + unique.
+ +It is expected that the wording of the success criterion will be updated to better reflect the + uniqueness requirement, likely in the future WCAG 3 due the complexities of changing the wording + for WCAG 2.
+This section will be updated with techniques for using multiple renditions when there is enough support in Reading Systems to broadly recommend their use.
